PENCIL-SI-IARPENER.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed October 20, 1913. Serial No. 796,196.

To all whom it may concern:

Be it known that I. SOREN JENSEN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles State of California, have invented new and useful Improvements in Pencil- Sharpeners, of which the following is a specification.

My invention relates to manually operated pencil Sharpeners, and relates more particularly to improvements on that class of pencil sharpeners as set forth in United States Letters Patent No. 965,907, issued to me on August 2. 1910, and one of the principal objects of the invention is to provide an improved sharpener having fewer parts than that shown in my patent heretofore mentioned. and which is simple in construction and efiicient in operation.

It is also an obiect to provide a pencil sharpener which slides upon the pencil and is always present for operation.

It is also an object to provide a pencil sharpener, which. when placed on the pencil will prevent the latter from rolling and afford a convenient finger hold or rest in using the pencil.

It is a further object to provide a pencil sharpener in which the sharpening medium may be readily replaced without the use of tools or machinery.

In the drawings accompanying this specification: Figure 1 shows a pencil with the sharpener, showing its application as a finger rest. Fig. 2 is a perspective view of the blade holding sleeve with the blade removed. Fig. 3 is a perspective view of the bladealone. Fig. 4 is a similar view of the two parts assembled in operative position. Fig. 5 is a view showing the method of holding the sharpener to sharpen the pencil therewith.

More specifically in the drawings. 6 designates the improved pencil sharpener which is shown as mounted in its normal inoperative position upon a pencil 7, as clearly shown in Fig. 1. and this sharpener consists mainly of a substantially tubular structure formed of sheet metal in which a plurality of slots are formed and the parts bent upon themselves intermediate certain cut-away portions on the edges thereof to form the clamping members 10 and 11. and intermediate of these on the oppositely disposed side from that where the edges of the integral blank forming the sleeve are brought together are the slots. Taking them in order from the clamping member 10 a slot 12 is formed into which the sharpened edge 14 of the blade 8 proiects and through which the pencil is introduced in the sharpening process. Separating the slot 12 from that designated 13 is a bridge 15 formed with sides and a flat transverse guard and adapted to straddle over and embrace the elongated blade 8.the transverse bar on the bridge engaging with the upper or outer side of the blade while the ears 16 formed just behind the bridge 15 engage the opposite side of the blade and form a seat therefor.

The slot 13 is rectangular in form. being not only intersected by the ears 16 but proiecting in the axial line of the structure is the spring tongue 17 which bears upon the under .or inner side of the blade. the tongue being provided with a slot 18 through which the lug 19 formed on the blade 8 is projected.

Intermediate the portion of the inner end of the tongue 19 and the very remote port on provided with the slot 18. an indentation or depress on 21 is formed against which the shoulder 22 on the blad abuts.

the tension of the tongue 17 ho d ng the shou de secu ely in the slot 18 and bind ng the b ade suit c entlv between the trans erse bar of the bridge 18 and the ears 16 to form a good hold.

In the operation of the device the end of the pencil to be shar ened is inserted from the s de provided with the s ts in through the slot 12 and in contact with the b ade t, the thumb and first finger grasping the slee e around the clamp po tion 10 and the po t ons of the sleeve 23 intermediate the brid e 15 and the clamp 10.

WVhat I claim is:

1. A pencil sharpener. comprising a tubular bodv member fo med with a pair of longitudinallv extending slots on one side thereo a b idge separat ng said slots. a removable blade extend ng beneath said bridge with its cutting edge arranged across one of the slots in the bodv member. ears projecting from the sides of the other slot beneath the blade. integral means on the bodv member for detachably engaging the blade. comprising a spring tongue having a slot therein. and a finger on the blade engageable with said slot.

2. A pencil sharpener, comprising a body member adapted to slide upon a pe'r'iil'ha'v mg a longitudinally extending slot therein,

a bridge member formed thereon, a spring" tongue extending'toward the bridge having a slot therein, a removable blade extending beneath the bridgewithits cuttingedge arranged across the slot, a'finger onsai'd blade:

engageable with the slot in the tongue, whereby the blade is held in position. i

3; Apencil sharpener, comprisinga body member adapted to slide on "a peneil and formed with pencil :ela-mping members and having a longitudinally extending slot, a

bridge member, a pair of i'nturned ears adthe tongue, said blade supported on"- said v Ears and extending beneath the bridge them er.

Copies of this patent may be obtained for 'day of October, 1913.

*4. 'A'pencil sharpener, comprising a body finember formed 'sub'st'antially' as asle'evee'arranged to slide 'u'po'nafpencil and'clamped said bridge,-ears=-formed on the sides of the slot, and a sharpening blade having a finger formed on its end oppositely disposedzfrorn the sharpened end thereof, 'said finger being inserted in the slot in said-"tongue and engaging said bridge and said ears and resiliently held in position by' saidtongue the whole when fastened upon a pencil adapted to form afinge'r rest. t

In witness that I'claim the foregoing I have hereunto subscribed my name this 13th SOREN JENSEN.
